MAP05: UAC Executive Areas, Sub-Basement Entry (Perdition's Gate)

MAP05: UAC Executive Areas, Sub-Basement Entry is the fifth map of Perdition's Gate. It was designed by Tom and Bob Mustaine and uses the music track "Maximum Horsepower" by L.A. Sieben.

Essentials
At the start, go through the door on the right within view and go up the stairs in front. Go down the stairs to the left and enter the opening in this room to reach the outside area. Go down the stairs to your left then climb up the stairs in front to reach the exit teleporters.

Secrets

 * 1) At the starting area, go down the stairs to your left (west) and press on the northern side of the northmost block to lower a supercharge. (sector 204)
 * 2) Come back to the starting area. This time, go south, then go up the stairs to the east, and open the door. Part of the wall straight ahead of you (east) is misaligned. Press it to reveal a room with six health bonuses, a backpack, and two boxes of rockets. (sector 99)

Bugs
A megaarmor (Thing 193) in the east has no flags set for any of the three difficulty classes, so it does not actually appear in the level. At the same position is an armor at skills 3-5, so the megaarmor was probably intended to appear at skills 1-2.
